Re: Power Supply Option


I have 3 bitx 40 v3 and all run at 13.8 v
I run them almost all the time with ft8 or jt65
I have oversize heat sinks on each.
Output around 8watts
Powersupply is well filtered plus extra filters inside the rig

Well that definitely is the power requirement for the Yaesu but I was running my bitX40 On a computer power supply that I tweaked to 13.8 V And it was running fine, no issues. I even was doing digital modes with it, FT8 specifically. I’ll make sure I use the proper power requirement for my micro bitx but as a real world example the bitx40 did run on 13.8v and finals really didn’t feel hot at all. Maybe I was lucky.

Good to know your Yaesu is fine with 13.8v.
Unfortunately, R141 on a stock Bitx40v3 is not.

There should be some tolerance like 10% +/-  on the voltage applied that shouldn’t hurt or hinder it. My Yaesu takes 13.8v by t 12v on the line works just as well
